Then we want to give predictions for currently unknown superheavy elements Z=119 and Z=120.
Particulary interesting is the nucleus \(^{302}\) 120,
as two unsuccessful attempts to produce it have already taken place in GSI,
providing a cross-section limit of 560 fb [1]} or 90 fb in
[2]}, and in Dubna [3]}, providing the limit of 400 fb.
The cross-section estimates [4]} do not support a possibility
of an easy production of this SH isotope in the laboratory.
It is worth noting that with the barrier of the order of 10 MeV, as obtained in the
frame of the self-consistent theory [5]}, producing superheavy Z=120 nuclei
should not pose any difficulties.
We chose these two cases of fusion reactions for which our predictions are the most optimistic.
For Z=120, it turned out to be the reaction: \(^{249}Cf(^{50}Ti,xn)^{299-x}120\) . The corresponding excitation function is shown on the right side in Fig. REF .
The largest cross section about 6fb is expected for the 3n and 4n evaporation channels.
One very important remark is required here: carrying out this reaction would require a change
of the projectile from \(^{48}Ca\)  used successfully up to now to \(^{50}Ti\)  with which no hot SHE synthesis was completed successfully.
Generally, prospects for the synthesis of element Z = 120 are
considerably worse than those for Z = 119. To obtain Z=119, our calculations prefer the \(^{252}Es(^{48}Ca,xn)^{300-x}119\) 
reaction, for which the synthesis cross section of about 0.2 pb in the 4n channel at \(E_{c.m.} \simeq 220 \)  MeV is expected. This case is shown on left panel in Fig. REF .
